Door Locking Device

ABSTRACT

A device including a doorknob, rotating disc implements, two steel connecting wires, two connecting rods, and weak-link connectors configured to disable the steel connecting wires when an excessive force is applied to the doorknob. One of the connecting rods comprises a spring loaded connecting rod configured to engage a threaded hole of a sliding bolt. The other connecting rod comprises a connecting rod configured to engage a separator pinion in the sliding bolt. The spring loaded sliding bolt enables the device to be positioned in a locked or unlocked condition. The device is configured to be installed in the center of a door to secure the door to a door frame. The door and door frame may each be made of wood or steel.

BACKGROUND OF THE RELEVANT PRIOR ART Field of the Invention: TechnicalField

The Skiles Locking System, S. L. S. incorporates the existing Kwiksettubular locking cylinder in its operation. The S. L. S. Locking Systemutilizes multiple internal spring loaded sliding bolts and also multipleinternal spring loaded floating locks within the spring loaded slidingbolts. The S. L. S. rotating discs which are attached to the Kwiksettubular locking cylinder operate independently of each other yet, arelocated on the same Kwikset tubular locking cylinder.

BACKGROUND ART

The Skiles Locking System, S. L. S. incorporates the existing Kwiksettubular locking cylinder in its operation. The S. L. S. Locking Systemutilizes multiple internal spring loaded sliding bolts and also multipleinternal spring loaded floating locks within the spring loaded slidingbolts, unlike the Kwikset tubular system.

The door (Fig. E) is easily closed and locked just by pushing the dooron its hinges (Fig. E) into its frame, and activating the singular doorlock mechanism from either “inside or outside” of the dwelling unlikeSaunders, which can only be manually activated and locked once inside.In the S. L. S. Locking System, rotating the doorknob (Fig. A) is notnecessary to activate the S. L. S. Locking System as is required in the“Saunders System.” This unique feature of the S. L. S. Locking System(Fig. A) enables multiple internal spring loaded bolts (Figs. B & C)within the door (Figs. C & E) to be activated immediately andsimultaneously after closure of the door (Fig. E) creating a safe,secure and defended position for the occupants without having toactivate “additional locks,” dead bolts or keyed mechanisms in the door,saving precious seconds and possibly lives in the process.

BRIEF SUMMARY OF THE INVENTION

A mechanized system of multiple internal spring loaded sliding bolts andinternal spring loaded floating lock mechanisms located inside of thedoor. The S. L. S. Skiles Locking System protects the occupants andtheir property from unwanted intruders, harm and theft. These internalspring loaded sliding bolts and their internally located spring loadedfloating locks are interconnected with and to a centrally positioneddoor knob mechanism and to the S. L. S. rotating discs which allowactivation of the locking system mechanism either “inside or outside” ofthe dwelling into the locked or unlocked position. The S. L. S. SkilesLocking System is also activated inside or outside of the dwelling witheither a key, “button” (inside) or “electronic keyless entry device,”allowing the door to be unlocked and opened. This can be done fromeither side of the door, (inside or outside) unlike the Saunders lockingsystem, which allows operation only from the inside. The samesimultaneous movement and action in the S. L. S. Locking System isaccomplished (Fig. B) with all multiple internal spring loaded lockmechanisms.

When the doorknob is compromised (Fig. I) the S. L. S. mechanisms (Fig.J) will remain locked in place (Fig. K). The wire connectors between theinternal spring loaded bolt locks and the S. L. S. door knob mechanism(Fig. I) will be broken by force. The steel connecting wires onceseparated from the S. L. S. doorknob mechanism and their respectiveinternal spring loaded bolt locks cannot be reattached. The lockedposition of the S. L. S. mechanism (Fig. K) cannot be unlocked manuallybecause the connecting wires (Fig. I) are unreachable by the intruder.

When the doorknob is compromised by force, (Fig. I) adverse pressure isapplied to the mechanism and its connections. An incorporated“weak-link” (Fig. I) is built into the connecting wires. (Fig. J) Thispart (Fig. J) is made from a softer and weaker metal (brass) as comparedto the (steel) connecting wires (Fig. J) which “connect” the S. L. S.internal spring loaded bolt locks to the S. L. S. doorknob mechanism.(Fig. I) When compromising force is applied to the S. L. S. doorknobmechanism, (Fig. I) the connecting wires (Fig. I) will separate at the“weak-link” (Fig. I) and disconnect the attachment to the S. L. S.internal spring loaded bolt locks (Fig. J) and the S. L. S. doorknobmechanism (Fig. I). When this separation occurs, the internal springloaded bolt locks (Fig. K) will remain in the “locked” position (Fig. K)by way of the internal springs within the bolt mechanism, (Fig. K)providing continued force upon their respective bolt locks within themechanism. (Fig. K) This “locked” position of the door within its frame(Fig. K) cannot be reversed manually or otherwise because of thedisconnection of the two mechanisms (Fig. I) within the system and door.

DETAILED DESCRIPTION OF THE INVENTION

1. Internal spring loaded bolt locks are simultaneously activated by akey, button or remote electronic device.

2. When the doorknob mechanism is compromised, (Fig. I) the internallocking mechanisms will remained locked in place.

3. The S. L. S. locking mechanism with the internal spring loaded boltlocks are completely contained within a brass cylinder within the door.
